Branching object for Orbital branching.
Variable_ is the set id number (redundant, as the object also holds a pointer to the set.

virtual void CbcOrbitalBranchingObject::previousBranch | ( | ) | [inline, virtual] |
Reset every information so that the branching object appears to point to the previous child.
This method does not need to modify anything in any solver.

virtual void CbcOrbitalBranchingObject::print | ( | ) | [virtual] |
Print something about branch - only if log level high.
virtual CbcBranchObjType CbcOrbitalBranchingObject::type | ( | ) | const [inline, virtual] |
Return the type (an integer identifier) of this
.
Implements CbcBranchingObject.

virtual int CbcOrbitalBranchingObject::compareOriginalObject | ( | const CbcBranchingObject * | brObj | ) | const [virtual] |
Compare the original object of this
with the original object of brObj
.
Assumes that there is an ordering of the original objects. This method should be invoked only if this
and brObj are of the same type. Return negative/0/positive depending on whether this
is smaller/same/larger than the argument.
virtual CbcRangeCompare CbcOrbitalBranchingObject::compareBranchingObject | ( | const CbcBranchingObject * | brObj, | |
const bool | replaceIfOverlap = false | |||
) | [virtual] |
Compare the this
with brObj
.
this
and brObj
must be os the same type and must have the same original object, but they may have different feasible regions. Return the appropriate CbcRangeCompare value (first argument being the sub/superset if that's the case). In case of overlap (and if replaceIfOverlap
is true) replace the current branching object with one whose feasible region is the overlap.
int CbcOrbitalBranchingObject::column_ [private] |
Column to go to 1.
Definition at line 354 of file CbcSymmetry.hpp.
int CbcOrbitalBranchingObject::numberOther_ [private] |
Number (without column) going to zero on down branch.
